In honor of the anniversary of Harry Potter and the Sorcerer's Stone book being released in the U.S., Yahoo Entertainment set out to find the biggest — and we mean biggest — Harry Potter fan we could find. The answer is right up there, in the video above. Her name is Katie Aiani.
Aiani’s Harry Potter obsession started when she was about 11 years old, and from there, she eventually became a full-fledged Potterhead. She started going to midnight movie premieres and fan conventions all over the world, and her latest obsession is going to Harry Potter Wizarding World at Universal Studios about three times a week.
